ANDRITZ Secures Major Contract to Modernize Mercury NZ Hydro Stations

International technology group ANDRITZ has further solidified its leadership in the New Zealand hydropower market after being selected by Mercury NZ Limited for a comprehensive modernization of the Maraetai I, Ātiamuri, and Ōhakuri hydro stations. This major contract, valued in the lower three-digit million-euro range, distinguishes ANDRITZ from its competitors through its proven track record on the Waikato River and its ability to deliver state-of-the-art manufacturing from its Austrian facilities. The project involves the supply of nine new turbines and 13 new generators, serving as a critical step in New Zealand's transition toward a 98% renewable energy grid by 2030.

Enhancing Grid Stability through Advanced Hydropower Refurbishment
Modernizing aging hydroelectric infrastructure is essential for maintaining long-term operational reliability and increasing energy output without expanding physical footprints. By replacing equipment built in the 1950s and 60s, ANDRITZ will implement new turbines, generators, and governors that significantly improve efficiency and water flow management. This upgrade will increase the combined installed capacity of the three stations by 76 MW, totaling 452 MW. This enhancement adds 87 GWh of annual generation, ensuring that these historical assets continue to provide the reliable, baseload power necessary to support a sustainable energy future and preserve the local environment.

Comprehensive Engineering and Strategic Market Positioning
The scope of the agreement covers the entire lifecycle of the project, including the design, manufacturing, installation, and commissioning of the units and their associated auxiliaries. All core components will be produced at ANDRITZ’s specialized facilities in Austria, ensuring high-performance standards that meet the rigorous demands of Mercury’s 100% renewable portfolio. This partnership marks the fourth major collaboration between the two companies, following successful rehabilitations at the Karāpiro, Aratiatia, and Whakamaru stations. By consistently securing these large-scale infrastructure projects, ANDRITZ continues to demonstrate a competitive edge in delivering specialized electromechanical solutions that stabilize and grow national renewable energy supplies.
